Apache 2.2.6 Installation problem

Unable to bind to adress, no listening sockets available

[swap]

I am a mechanical engineer with limited knowledge to software. I need Apache for a project with SQL query writing.

However, I'm unable to install Apache 2.2.6 as Im getting the following error message:

"<OS 10048> Only one usage of each socket address< protocol/network address port> is normally permitted. :make_socket:could not bind to address 0.0.0.0:80 no listening sockets available"

I read one of the posts where a user was facing similar problems and was asked to uncheck the IIS option in Add/Remove Windows Components. I found that in my case it was already uncheked.

Please help. Thank you.

welcome to WebmasterWorld [webmasterworld.com], swap!

try:
netstat -an

it should give you some hints...

A very popular application is occupying port 80 (which is needed for Apache, as that's the standard HTTP port), and that would be the Skype, which has a setting called "Use port 80 and 443 as alternatives for...", and if that's checked by the time of installing or starting Apache, then Apache will not succeed.

This is just one possibility, you may need to use the

netstat -anb

command as it was mentioned by phranque, that will show you which applications are listening on port 80 (look for 0.0.0.0:80), so you know which application needs to be removed, or its settings to be adjusted.

Could be IIS the web server that comes with Windows is running...it would likely default to port 80.
